Two counts of first-degree murder of a police officer and three counts of attempted first-degree murder of an officer were filed Wednesday against two suspects connected to the ambush that killed two St. John the Baptist Parish deputies last week.

The charges were tacked on to those previously filed against Brian Smith and Kyle Joekel, Louisiana State Police said.

New charges were also set in place on one of the other five suspects.

Brittney Keith was charged with two counts of principal to first-degree murder of a police officer and three counts of principal to attempted first-degree murder of an officer.

The new counts came on the same day that Joekel was released from an area hospital. He and the other suspects are now at the St. Charles Parish Correctional Center.

Deputy Brandon Nielsen, 34, was laid to rest Wednesday afternoon, two days after funeral services were held for Deputy Jeremy Triche, 27. Deputies Michael Scott Boyington and Jason Triche remain hospitalized from injuries sustained in the shooting last Thursday.

"Our prayers are with the families of the fallen and injured deputies, the sheriff's office and all our our greater law enforcement family," said State Police Col. Mike Edmonson. "State Police is committed to diligent, thorough and complete investigation of these horrific acts."
